The Multiquip 13012Z5K004 is a genuine OEM Piston Ring Set (0.50) designed for GA3.6HR generators, MC12PH concrete mixers, and MVH308GH and MVH208GH heavy-duty reversible plate compactors. As a direct OEM replacement, this oversize ring set is manufactured to the same tolerances as the original, ensuring a correct fit within the engine bore without rework or custom fitting. Sourced directly through Multiquip's authorized parts network, the 13012Z5K004 is the right choice when rebuilding or re-ringing an engine during a top-end overhaul. Verify your equipment's model code against the fitment list to confirm compatibility before ordering.
Key Features
- OEM-Grade Ring Seal Integrity — Manufactured to the same compression and oil-control specifications as the original rings, maintaining proper combustion chamber seal and oil film management across all compatible engine applications.
- 0.50mm Oversize Specification — Sized for engines that have been bored 0.50mm over standard, making this ring set the correct choice when replacing rings after a cylinder bore service or hone.
- Broad Cross-Equipment Fitment — Compatible with GA3.6HR generators, MC12PH concrete mixers, and MVH308GH and MVH208GH reversible plate compactors — one part number serving multiple machine families sharing the same engine platform.
- Compression and Oil Control Restored — Worn or broken piston rings cause blow-by, excessive oil consumption, and loss of power; installing a fresh OEM ring set restores proper cylinder pressure and protects the engine from accelerated wear.
- Genuine Multiquip OEM Part — Supplied as an authorized OEM replacement, ensuring correct ring gap, material grade, and coating match the engine manufacturer's original design intent for this bore size.
Piston rings seal the combustion chamber between the piston and the cylinder wall, performing two critical jobs: containing the pressure generated during combustion so it drives the piston downward effectively, and controlling engine oil so it lubricates the cylinder without burning off in the combustion process. A compression ring that is worn, stuck, or broken allows combustion gases to escape past the piston — a condition known as blow-by — which robs the engine of power and causes rough running. Worn oil-control rings allow excess oil to enter the combustion chamber, leading to blue smoke, fouled spark plugs, and increased oil consumption. Replacing the piston rings with the correct oversize set during an engine rebuild restores compression, reduces oil consumption, and returns the engine to full operating efficiency.
